Cartesian Flowchart The influence of René Descartes is hard to describe, and harder to demonstrate, but there are a few clues out there. Even if you discount most of his contributions to mathematics, physics, and philosophy, the phrase ‘Cogito, ergo sum’ (‘I think, therefore I am’) and the fact that we use the term ‘Cartesian geometry’ are a bit of a giveaway. With the ‘cogito’, Descartes was attempting to establish a ‘first principle’, upon which other ideas could be based.

SpongeBob, via Wikimedia Commons I was not familiar with Eric Shaw, nor have I ever really watched SpongeBob SquarePants, though I am familiar with the characters through their impact on popular culture. According to Wikipedia, Mr Shaw is a television writer, credited with a number of episodes of SpongeBob, along with a number of other works. With that in mind, I was a bit confused when I heard the reference to Eric Shaw on Smashing Security Episode 476, in a conversation bet

Hacker Silhouette, via Wikimedia Commons They want to help keep people safe. That’s a motivation I certainly support, but it’s important to be sure that your actions actually support your goal. On the 1-Dec-2025 episode of Cybersecurity Today, host David Shipley (whom I have mentioned before) talked about a new (at that time) website called Stop Hacklore! They describe themselves as “a group of current and former CISOs and security experts” who “want to offer guidance that ma

Phrack, via https://phrack.org/ Language is constantly evolving, not only by time and location, but also because of usage and changing cultural associations. When I think of the word “manifesto”, the example which leaps to mind is the Communist Manifesto, obviously due to the title, but also because it is short and clearly laid out. Manifesto is defined as “a written statement declaring publicly the intentions, motives, or views of its issuer”, and such statements are general

Tweety from Looney Tunes and Merrie Melodies, via Wikipedia Though certainly an iconic figure, I’ve never been a particular fan of Tweety . I find earlier versions of the character cruel and malicious, while later versions (possibly, I’ll admit, because of those earlier versions) seem faux-innocent and cruelly manipulative. Sylvester , on the other hand, is often a more relatable character, especially when he recognizes that cats eat birds and struggles to control his baser i

Boötes Void , aslo known as the “Great Nothing”, via Wikipedia.org “He who fights with monsters should be careful lest he thereby become a monster. And if thou gaze long into an abyss, the abyss will also gaze into thee.” Friedrich Nietzsche, Beyond Good and Evil, Ch IV, Section 146, Via Project Gutenberg Nietzsche is a very interesting figure, whose work is often admired and/or criticized, but seldom understood. It does not help that he suffered bouts of ill health throughou

“Martha Root”, dressed as Pink Ranger, Chaos Computer Club, 2025 I feel conflicted. On the one hand, it was illegal. On the other hand, they were bad people and it was very cool. I once attempted to describe the “ hacker mindset ”, which is less about technology, and more about trying to find innovative ways to do things – for many “old-school” hackers, it was far more about solving puzzles. Over the years, the word “hacker” has become more and more difficult to define. Depen
